GAS-RANGE DOOR.

Specification of Letters Patent. Patented Sept. 21, 191 5.

Application fi1ed Marc1 1 3, 1915. Serial No. 11,364.

To all whom it may concern V Be it known that I, Mnann A. PossoNs, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Gas-Range Doors, of which th e following is'a specification, reference being had therein to the accompanying drawing. V

My invention relates to improvements in gas range, doors. I v

The object of my invention is to provide a gas range door fitted with a glass panel in which the glass panel is so supported that, that portion of the panel which the heat strikes first is not covered with a binding, so that when the oven is lighted, the heat at once reflects uponthe whole inner surface of the panel. Thi s'allows a perfectly even expansion of the glass and, therefore, i.t is less liable to. break.

Another object of my invention is'to provide a simple, cheap and effective lining for the door constructed and arranged .to support the glass panel and at the same time providing means for attaching the panel fastening means. i

A still further object of myinvention is to provide-a simple cheap and effective door of this character having certain details of structure and operationhereinafter more fully set forth.

In the accompanying drawings: Figure 1 is a rear perspectiveview of an oven door embodying my inventiom Fig. 2 is a vertical sectional view taken on the line 22 of 1. Fig. 3 is a perspective view partly broken away of the lining, showing the glass in position and looking from the opposite side. fromthat shown in Fig.1, 7

Referring to the drawings, 1 represents my, improved oven door which is of the usual form having at one end thehinges 2, and at the opposite end the handle 3, all of which is of theusual structure and needs no. further description, as this. forms no part of my invention. The door 1 has its central portion. cutawayforming a large central opening nearly as large as the-door and which is covered by the glass panel' t, by means of which the whole contents of the oven can be readilyinspected. The lower edge of the door 1 is'provided' with a smallglass panel 5, secured to the door by meansof bolts 6 and which is so posi-.

tioned on the door that the burners within the lower end of the oven may be readily inspected.

The door ispractically cast and of a hollow form, as fully shown in Fig. 1 of the drawing. The outeredge of the hollow frame or form of whiclrthe door is constructed is provided with lugs 7 arranged at proper intervals around the frame adjacent its outer edge for the purpose later described. The frame is provided with a flange 8 extending therearound a short distance from its inner edge 9. Adjacent the inner edge 9 of the frame is a flange 10, which does not extend out as far as the flange 8, but allows for the thickness of the lining and the glass panel, as will be later described. The frame of the door is provided with inwardly extending bosses 11, intermediate the flanges 7 and 8, and these are arranged at the proper interval around the frame and are provided with screwthreaded openings into which screws 12 pass (flor fastening the lining to the frame of the oor.

The lining 13 of the door is preferably made of sheet-metal and has at its outer edge the inwardly turned flange 14, which isof a width to engage the lugs 7 of the door-frame and bring the outer faces of the lining 13 flush with the inner face 15' of the door-frame. The central portion ofthe panel 13 is cut away and is turned inwardly at 16 and again turned at right angles thereto, as indicated at 17 which forms a: ledge upon which the glass panel rests. The portion 16 abuts against the flange ,8, while the portion 17 abuts against the flange: 10, whereby the solid backingfor the lining is provided. By this structure it will be seen that a receiving ledge is provided around the entire door-frame for receiving a glass panel 4. The lining 13 is provided with a number of openings through which the screws 18 pass and by means of which the lining is rigidly secured to the inner face of the oven door-frame. v

. The inwardly turned flangeor portion 16 of the lining is provided with slots 19 and 20 at their lower ends through which extends the stationary lugs 2L and 22- carriedby the inner face of the lining and whichare adapted to overlap the glass panel and hold the same against inward movement. These lugs 21 and 22, as clearly;

shown, are comparatively small and engage very little of the glass panel and thus allow the heat to engage practically the whole of the panel and thus prevent an uneven heating of a portion of the panel, which would result in the breaking of the glass panel.

Pivotally secured to the inner face of the lining 13, at 23 and 24-, are the panel lookglass panel. The locking members 25 and 26 are of small area so that they will cover a very small portion of the glass panel and thus prevent the same from being cracked, or otherwise injured by the heat, as heretofore stated in respect to the lugs 21 and 22. By this arrangement it will be seen that the members 25 and 26 are moved inwardly when it is desired to remove the glass panel 4 for cleaning or any other purpose and the upper end forced inwardly and then raised outwardly from behind the lugs 21 and 22.

I am aware that glass panels have been secured in oven doors by strips of metal, as shown in Patent No.'1,108,8l0, and in such cases the glass in the rear of the strips is not heated as rapidly as the unexposed portion of the glass panel and, therefore, the

panel is often cracked. Vi hile arranging the panel, as shown in the drawings and heretofore set forth,the entire glass panel is exposed and receives the heat directly from the oven and will not crack.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. The combination with an oven door having a central opening, a ledge surrounding the opening, a glass panel resting'upon the ledge, stationary lugs carried by one side of the door and extending through the ledge and movable members carried by the opposite side of the door and adapted to extend over the panel, substantially as shown and described.

2. The combination with an oven door having a central opening, a ledge surrounding the opening on the inner face, inwardly extending lugs carried by the door and extending over the ledge on one side of the opening and movable members carried by the door and extending over the ledge on the opposite side of the opening.

3. The combination with an oven door having a lining formed of sheet-metal and having a ledge formed thereon for supporting a glass panel and lugs carried by the inner face of the lining and extending over the ledge for securing the panel within the ledge in the lining.

4.
